title: Picture archiving communication system does not decrease the number of radiographs needed to evaluate the trauma patient.
abstract: BACKGROUND
  Picture Archiving Communication System (PACS) is a sophisticated software and hardware package that enables clinicians to retrieve, review, and digitally manipulate radiographs from computer workstations throughout the hospital. PACS was instituted at Brooke Army Medical Center in July 1993.
  
  
  METHODS
  Fifty consecutive trauma and 50 consecutive motor vehicle crash (MVC) trauma admissions to an urban trauma center were reviewed before PACS (January 1993) and 18 months after PACS was instituted (January 1995). Patients were compared by the number of radiographs needed during the initial evaluation by type and total. The trauma groups were subdivided by mechanism and also compared. Demographic and physiologic data were collected for each patient.
  
  
  RESULTS
  There are no differences in the demographic and physiologic data between groups. For the 50 consecutive trauma admissions, only two areas of statistical difference were found: more chest films were obtained in the MVC PACS group and more pelvis films were obtained in the gunshot wound pre-PACS group. For the 50 consecutive MVC trauma admissions, the PACS group had more chest and total radiographs per patient than the pre-PACS group. More computed tomographic scans of the neck were obtained in the PACS group.
  
  
  CONCLUSIONS
  PACS did not decrease the number of radiographs needed to adequately and fully evaluate the trauma patient.
